A 17-year-old Florida juvenile named Corey Johnson told authorities that he fed himself a diet of jihadist videos and read the Quran “to give him courage” before stabbing one boy to death and seriously injuring two others at a sleepover last week. Johnson, who has been charged with first-degree murder in the death of 13-year-old Jovanni Sierra, was previously under investigation for “alleged violent tendencies,” according to the Palm Beach Post.

Johnson was among those invited to the sleepover, which was being held to celebrate Sierra’s birthday at the Ballen Isles Country Club home of friend Kyle Bancroft. Authorities report that Johnson and Bancroft spent the previous evening watching ISIS videos on the internet. Johnson told police that he woke up at 4:00 in the morning with the sudden desire to kill Bancroft’s mother, his brother, and the birthday boy, all of whom were sleeping.

“In his statement, Johnson advised he stabbed the victims because of his Muslim faith,” said the affidavit against the murderer.

Johnson first attacked the sleeping Sierra, stabbing him multiple times before slitting his throat in a manner consistent with the videos he and his friend had watched. Sierra’s cries of pain woke the mom; she went upstairs and was immediately attacked by the Muslim teenager. Police say she was stabbed at least a dozen times before falling down the stairs. Dane Bancroft, Kyle’s brother – also 13 – attempted to intervene on behalf of his mother and took 32 stab wounds for the trouble. The boy’s father proclaimed his a hero in an interview with the paper.

“He saved his mom,” the father said.

Thus far, the Southern Poverty Law Center has yet to update their archives with a listing of this religiously-motivated “hate crime.”

Nor, apparently, was it a priority for Palm Beach authorities to recognize Johnson as the terrorist threat that he clearly was. The paper reports that he was angry at the 13-year-olds for referring to celebrities as “gods” and mocking his Islamic faith, but this wasn’t the first time Johnson had signaled his fanaticism. He has been investigated by the Palm Beach Sheriff’s Office for communicating with ISIS online and calling in threats to a British school.

Had he been a white “alt-right” whatever, perhaps the police would have taken this threat more seriously. But since he was a Muslim, well, you know, we have to give them every benefit of the doubt. Don’t want to appear bigoted or “racist,” do we?
